Keeping Track of "Caly"
Caly isn't likely to wonder off off, but with a remote camera and monitoring station online 24-hours a day, USGS and partners at the State of Hawai‘i Division of Forestry and Wildlife, University of Hawai‘i, and the USFWS can learn how an extremely rare plant is responding to changes in environmental conditions.
Sniffing Out Better Tools for Addressing Avian Botulism
Dogs have great olfactory abilities and wildlife biologists think they can help endangered waterbirds in Hawai‘i. Dogs are being trained to sniff out the endangered ducks (koloa maoli (Anas wyvilliana) and Laysan ducks (A. laysanensis)) that die of avian botulism.
Hawaiian Birds Rapidly Colonize Young Restoration Forest
Forest birds on the island of Hawaii are responding positively to being restored in one of the largest, ongoing reforestation projects at Hakalau Forest National Wildlife Refuge, according to a new study released July 10 in the journal Restoration Ecology.

Seasonality and prevalence of pollen collected from Hawaiian nectarivorous birds
Hawaiian nectarivorous forest birds play a vital ecological role as pollinators in Hawaiian ecosystems. However, little is known about what nectar resources are utilized by Hawai‘i’s nectarivorous birds, how seasonality influences nectar availability, and how nectar preference differs by bird species. We sampled pollen from the heads of ‘i‘iwi (...
van Dyk, Kathryn; Paxton, Kristina L.; Hart, Patrick J.; Paxton, Eben H. Regeneration of Metrosideros polymorpha forests in Hawaii after landscape‐level canopy dieback
Questions(a) Have Metrosideros polymorpha trees become re‐established in Hawaiian forests previously impacted by canopy dieback in the 1970s? (b) Has canopy dieback expanded since the 1970s? (c) Can spatial patterns from this dieback be correlated with habitat factors to model future dieback in this area?Study SiteAn 83,603 ha study...
Mertelmeyer, Linda; Jacobi, James D.; Mueller-Dombois, Dieter; Brinck, Kevin W.; Boehmer, Hans Juergen Economical environmental sampler designs for detecting airborn spread of fungi responsible for rapid `Ōhi` death
We designed two new samplers for monitoring airborne particulates that rely on either natural wind currents (Passive Environmental Sampler) or a battery-operated fan (Active Environmental Sampler). Both samplers are significantly less expensive than commercial devices such as Rotorod® and Burkard Samplers that are used in the agricultural and...
